Used bike I'm looking at vs my current bike *and notes on how to get back to my current fit. Both are marketed as an "endurance geometry".
Prospective Bike : Current Bike
Stack: 565 : 598 *go up 3 spacers, from bottom to top of steerer tube
Reach: 383 : 391 *90mm stem to 100 or 110mm
BB to top seat tube: 540 : 553 * +1.3cm seat tube exposed. I compared to a 58cm Spec Roubiax which is also 540mm
Seat tube angle: 74 : 73 *new bike has more of a setback on seat tube
Head tube angle: 73 : 73.8
Make sense?
